Notable Holders

STZ ranks #453 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

Capital International Investors has trimmed its STZ position for two straight quarters, cutting it by $772.8M while still holding $116.1M.

STZ is down 0.4% today, but institutions show net buying of $4.4B this quarter — a divergence between today's price move and the underlying institutional flow.

Game Theory Scenarios

Neutral— Wait & Watch

Mixed institutional breadth, thin insider flow — neutral

Signal Basis

Aggregate 13F position value rose ~$4.43B quarter-over-quarter, yet net sellers (584) outnumbered net buyers (397) and exits (120) exceeded new positions (102) — dollar growth without breadth. The 90-day insider record shows only one ~$85K Form 4 sale (2026-02-17) with a 0.0 confidence score, offering essentially no directional confirmation.

Confirmation

A next-quarter reversal to net-buyer breadth among 13F filers, paired with meaningful insider purchase activity, would strengthen a bullish tilt.

Invalidation Risk

Widening institutional net distribution combined with recurring insider selling would invalidate this neutral read and suggest bearish pressure.

AI-assisted, sourced directly from institutional holders' SEC EDGAR Form 13F filings, covering historical data only. Should not be the sole basis for any trade.

Smart Money Convergence

STZ does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
